The Baltimore Ravens are the underdogs in this Sunday's Super Bowl, going up against the San Francisco 49ers. Now, there have been bigger underdogs. And yes, the Ravens are not the lowest-seeded team to make it to the Super Bowl. But the Ravens have beaten the odds in another way. NPR's Mike Pesca talked to some football numbers guys and has this report.

When Sandy brought high winds and a massive storm surge, the city of Long Beach on Long Island was among the hardest hit. The loss of the city's high school locker and equipment rooms may not have been the most tragic event, though it did make it unlikely that the school's football team would finish its season. But this weekend, the Long Beach Marines did manage to field a team. NPR's Mike Pesca reports.

Olympic winners like gold medalist Claressa Shields have said the games were a learning experience, but what were they learning? Hard work? Sure. Sportsmanship? Maybe. The metric system? Certainly not.

U.S. judo competitor Kyle Vashkulat competes at 100 kg, which he knows means he weighs 220 lbs. But does he know height?

"We were in a sauna, and the guy's telling us the height of the boxers, and he's like, 'Yeah, this guy's like, 1.7 meters' — and we're like, 'How tall is that?'" Vashkulat says, laughing.

Four years ago, Irish boxer Paddy Barnes lost to China's Zou Shiming by a score of 15-0 in Beijing. Today in London, Barnes fought his way back into their match to tie Zou at 15-15 — but he still lost. Barnes accepted the decision, but the result might confuse anyone who isn't familiar with boxing's scoring system.

There seems to be a vague logic that dictates which Olympic sports are conducted against a backdrop of noise, and which operate in a cone of silence.

For the most part, the more a sport depends on a fine motor skill, the quieter the spectators are meant to be. Shooters squeeze triggers before mostly hushed crowds. But in many shooting disciplines, the competitors line up in a group and can shoot at any point during their time allotment. So not only is gunfire ringing in their ears, crowds often become noisy, depending on the results.

Now, as we cover the Olympics, some of you have asked for spoiler alerts, but for this next report that is probably not necessary. NPR's Mike Pesca is taking us inside the world of India's men's field hockey team. We're not too worried about spoilers. Not just because most Americans don't care much about field hockey, but because the Indian squad has done a pretty good job itself of spoiling things. As Mike reports, the team's record tracks with the overall state of the Indian Olympic effort.

On the same day cyclist Bradley Wiggins became Great Britain's most-decorated Olympian, Daniel Harris, a 28-year-old cycling enthusiast, was killed when he was struck by a bus at an intersection outside Olympic Park.

It's hard to find a discipline that Team USA has dominated more than the women's sabre. The team is anchored by two-time medalist Mariel Zagunis. And before Zagunis was upset in the bronze medal match Wednesday, five of the six medals that had been awarded since 2004 went to Americans.

Eight Olympic badminton athletes have been thrown out of the London Games after being charged by the Badminton World Federation with "not using one's best efforts to win a match" — which is against the rules of the sport. Because even some journalists may have forgotten badminton's rules, it seemed time to take a fresh look.

When I say citius, you say altius; when I say altius, you say fortius. Or don't. That's fine, too, traditional even. But these Olympics have conspicuously defied traditional notions by having cheerleaders, in a few different styles, at a few different venues. In basketball, dance teams perform between matches. In beach volleyball, highly choreographed teams delight attendees.

Judo is a sport of leverage, strength, tactics and cunning. These attributes can appear to the uninitiated to be two people attempting to grab each other, without success, for five minutes. And then when no points are scored, they try to grab each other for another three minutes of overtime.

One of these gripping contests — the men's quarterfinals at 66 kg — has become the source of international indignation over a perceived injustice. But with the sport of Judo, an apparently firm set of circumstances can flip in an instant.

The Kentucky Wildcats beat the Kansas Jayhawks 67-59 Monday night in New Orleans, claiming their eighth NCAA men's basketball title and head coach John Calipari's first.

The Jayhawks trailed by 14 at halftime, and just 5 points separated the teams with about a minute left in the game. But Kansas couldn't get any closer to beating Kentucky, a team stacked with young talent that had dominated the whole tournament.

The national championship game in men's college basketball is set. The Jayhawks beat Ohio State in a close one and Kentucky got past Louisville.

At the nine-minutes-to-go mark in games one through four of Kentucky's romp through the NCAA tournament, the Wildcats have had leads of 13, 11, 18 and 30 points. So it was significant that the Louisville Cardinals actually found themselves tied with Kentucky at that nine-minute juncture.

The critique of University of Kentucky head basketball coach John Calipari is that he does what it takes to get his players, and they do what they want from there. Sure, this thinking goes, he's yelling at them from the sidelines whenever one — specifically Terrence Jones — puts up a 3-point shot from a step behind the arc. But he's not much of a coach.

In NCAA men's basketball, the Louisville Cardinals and Ohio State Buckeyes have qualified for the Final Four. Later today, two more teams will join them after Kentucky plays Baylor and Kansas faces North Carolina. With so much basketball peppered with reversals and upsets, it's hard to deny the madness of March. But, as NPR's Mike Pesca reports, most coaches try desperately to keep it at bay.

JACKI LYDEN, BYLINE: Every school invited to the NCAA basketball tournament has had a chance to play. So we thought we'd bring you details of every game. Well, maybe not details, but at least a mention from NPR's Mike Pesca. And what he lacks in specifics, he makes up for in rhyme.

It is Super Bowl Sunday, the biggest day in football. And therefore, the biggest day in defense or so the conventional wisdom goes. But the teams in today's game, the Giants and the Patriots, featured less-than-stellar defenses through the season.

The Super Bowl: an annualized marketing event-cum-gambling extravaganza. That they have to play a football game to justify the ads, gambling and Ines Sainz's career is still in the official rule book somewhere, but that rule book is now sponsored by the Gatorade G2 series. Why does Gatorade have more series than Telemundo?
